Answer:
A researcher is interested in the relationship between time spent browsing items in an online store and the total amount purchased from the store. The researcher selects a random sample of visitors to the online store and records the time spent browsing and the total amount of their purchase. The researcher will conduct a t-test for the slope of a regression line, where time spent browsing is the explanatory variable and total amount of purchase is the response variable. Which of the following would be an indication that the normality condition has been met?
A. A sample size that is less than 30
B. A histogram of the residuals that is centered at 0 and strongly right skewed
C. A dotplot of the residuals that is centered at 0, unimodal, and symmetric
D. A boxplot of the residuals that is centered at 100 and does not provide evidence of skewness or outliers
E. A scatterplot where total amount of purchase is the explanatory variable and time spent browsing is the response <em><u>variablemdnfnf</u></em>
Answer:
12 minutes
Option D
Step-by-step explanation:
Given that circuar gears P and Q start rotating at the same time at constant speeds.
Gear P makes 10 revolutions per minute and Gear Q makes 40 revolutions per minute.
Both gears start at the same time.
No of rotations per minute are 10 and 40
Difference is 30 in one minute
For 6 difference we must have exactly 1/5 minutes
which equals 12 seconds.
In 1/5 minutes or 12 seconds gear P would have completed 2 revolutions while Gear Q would have completed 8 revolutions thus making difference as 6.
